The invention discloses a flexible electrode and a flexible battery cell. The flexible electrode comprises a current collector and an electrode material layer, wherein the electrode material layer is coated on a surface of the current collector and comprises a plurality of segments of electrode material layers, and an interval is arranged between the two adjacent segments of electrode material layers. The flexible battery cell comprises a negative electrode, a negative electrode and a separator, wherein the separator is stacked between the positive electrode and the negative electrode, the positive electrode is the flexible positive electrode, the negative electrode is a flexible negative electrode, and a plurality of segments of positive material layers contained in the positive electrode are in one-to-one correspondence to a plurality of segments of negative material layers contained in the negative electrode. After the flexible electrode is assembled to form a battery, the battery formed by package comprises single batteries which are connected in series by sealing intervals; since the sealing intervals are not provided with electrode materials, the battery formed by package can be folded at the sealing intervals, and the flexibility of the battery is achieved.
